Twitter (now X) crops images aggressively when they don't match its expected dimensions. This tool resizes any photo to Twitter's exact profile, header, or post dimensions so your images display exactly as intended, without unexpected cropping.

Twitter automatically crops images that aren't the right ratio. A header photo at the wrong aspect ratio gets center-cropped; a post image that's too tall shows only a slice in the feed. Getting the dimensions right before uploading prevents every one of these problems.

Use this free tool to resize any image to Twitter's recommended pixel sizes in your browser, no account, no watermark, no server upload.

Questions & answers

Everything you might need to know before using the tool.

What size is a Twitter/X profile photo?+
Twitter displays profile photos at 400×400 pixels. The image is shown as a circle, so ensure the main subject is centered. Maximum file size is 2 MB for photos.
What are the Twitter header dimensions?+
Twitter header (banner) images display at 1500×500 pixels. The edges may be cropped on smaller screens, so keep key content in the center 1200×400 area.
What image size works best for Twitter posts?+
1600×900 (16:9 ratio) is ideal for tweet images. Twitter shows a preview crop in the feed, but clicking expands to the full image. Square 1200×1200 images also display well.
Does resizing reduce image quality on Twitter?+
Twitter recompresses all uploaded images (especially JPGs). Start with the highest-quality source you have and export at 100% quality to minimize double-compression degradation.

Your files are handled responsibly

Many tools (crop, sign, merge previews, AI watermark removal, upscaling, redact) run fully in your browser — your file never leaves the page. The rest (heavy conversions, OCR, video) upload over HTTPS to a private server and are deleted automatically after processing. Each tool's upload area shows which path it uses.
